WowAce

What steps will reproduce the problem?
1.  Added Sinestra>Wrack to text down as top priority.
2.  Put the gold checkmark next to "elapsed time".  Unchecked all other checkboxes, except "show duration", which automatically gets the grey checkmark.

What is the expected output? What do you see instead?
As soon as the Sinestra encounter is begun, I start getting many errors (I hear the fatality noise of buggrabber once a second).  As the fight progresses, health updates come less frequently until Grid2 completely fails.  I have seen it simply stop working, and other times will duplicate raid members (for example, I will see the same people twice in the 10m, and others wont be shown anymore).

I have only done 4 encounters on Sinestra with Grid2 thus far, I will continue to update this ticket as I acquire more info.

What Grid2 version and language of WoW are you using?

It was r619 I believe (a fairly recent release).

Do you have an error log of what happened?

Please provide any additional information below.
Will continue to update ticket with new info, please let me know if you need any further information.  Grid2 is by far the best Grid addon, despite this flaw!

Revision 624 should fix this bug.
